ASTM F 1534 : 1994 : EDT 1

1.1 This fire-test-response test method covers a procedure for leaching cushioning materials with water and determining changes in two specific fire-test-response characteristics: ( ) the surface flammability, per Test Method D3675 and ( ) the specific optical density of smoke generated, per Test Method E662.

1.2 This standard should be used to measure and describe the response of materials, products or assemblies to heat and flame under controlled conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire hazard or fire risk assessment which takes into account all of the factors that are pertinent to an assessment of the fire hazard or fire risk of a particular end use.

1.3 In view of the wide variation in potential service conditions, it is likely that results of this leaching test will not give a direct correlation with service performance for all applications. However, the test method yields comparative data on which to base judgments as to expected service of cushioning materials and is useful in research and development work.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
